THE DIGITAL 100: The World's Most Valuable Private Tech Companies

We've been valuing and ranking the world's most valuable digital startups for the last 5 years. We started with 25 companies, and this list soon expanded into the SAI 50+. Now it's the Digital 100.

Initially, this was just a list of startups. But the term "startup" has gotten very gray. Is Twitter still a startup? How about Pinterest?

So this year, we've expanded our search and analysis again. We found a ton more companies that are earning a lot of money and / or growing rapidly. The result is this year’s new and improved "Digital 100" — 100 of the world's most valuable private digital tech companies from around the world. India, China, and Russia are just a few of the countries that are represented.
